Advance Information
Quad High Side Switch
(Quad 15 mOhm)
15XS3400
The 15XS3400 is one in a family of devices designed for low-voltage
automotive lighting applications. Its four low RDS(ON) MOSFETs (quad
15 mOhm) can control four separate 55 W / 28 W bulbs, and/or Xenon
modules, and/or LEDs.
HIGH SIDE SWITCH
Programming, control and diagnostics are accomplished using a
16-bit SPI interface. Its output with selectable slew-rate improves
electromagnetic compatibility (EMC) behavior. Additionally, each
output has its own parallel input or SPI control for pulse-width
modulation (PWM) control if desired. The 15XS3400 allows the user to
program via the SPI the fault current trip levels and duration of
acceptable lamp inrush. The device has Fail-safe mode to provide fail-
safe functionality of the outputs in case of MCU damaged.
